Strengths & Limitations

Strengths

  • +Systematic review approach provides a broad overview of existing research.
  • +Focus on multiple key environmental impact categories.

Limitations

The study is a review, so it relies on the quality and consistency of the original LCA studies. The specific details of the integrated technologies and their LCA scopes can vary widely.

Reliability & validity

The reliability and validity depend on the quality of the original LCA studies reviewed. The systematic review itself aims to increase reliability by standardizing the analysis process.

Think critically

How can the wide range of GWI values be reconciled to provide clearer guidance for designers and manufacturers?
